Application inea irai-er. ai, ieri. seriaiio. eaaisa To all whom imag concern Be it known that I, THOMAS Ronnnicn, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Valves, of which the following is specification.

metal of disk the ports is eected. The

vbeing of slightly larger l @ne of the objects of this invention is to.

provide an improved valve of simple and economical construction in which a washer is dispensed with.

Another object is to` provide a valve which is reversible so that if one face becomes worn or damaged the other can be presented to the seat.

The invention is embodied in the example herein illustrated anddesoribed the features of novelty being pointed out in the claims.

' 1n the accompanying drawing-Figure 1 is a vertical section of a faucet containing thek invention. Figy is a section on the line wlooking down. Fig. 3 is a section on the line jij-y looking down. f Fig. 4 is a per.- spective view of the valve and its stems.

In the views 5 ordinary `water faucet. Within the case below the discharge of the faucet is a web or diaphragm 6 of metal having ports 7 the lower or inlet orpressure side of said diaphragm forming the valve seat.

8 designates the valve body which is of form, dat and smooth on both faces and provided with ports 9 corresponding substantially in size and form to those of the valve seat. rihe ports 7 and 9 are of such dimensions that the valve upon beingv turned, say, a quadrant or less a closing of valve body is pinned to the middle of an axially located stem 10 the opposite ends of which are notched or groovedas seen at 11. The valve body is thus, in effect, provided with two stems identical with each other. One of these stems is extended up through a central opening 12 in the valve seat, said opening diameter than that of the stem so as to admit a slight play of the valve laterally on its seat. The other stem extends downward through a central opening 13 in a web,- or spider 14 in a union- 15. The vcentral opening 13 is also ofy slightly'larger diameter than that ofthe stem so as not to interfere with the play of lThe web or spider 14 has additional openings 16 to perinitthe free passage of water or other fluid .the valve on'its seat.

to theffaucet. @n tliestem and vvinterposed Specification of 'Letters Patent. PatantedfDeQ. `r15, 1914;.'y

between the spider 1&1 and the lower side;y

of the valve body is a light coil spring 17 tending'to press the valve ybody toward its yso seat., The principal functionwof this spring n isto,liold the valve upfwhen the ports are open'because when saidkports are closed water pressure is kusually sufficient to hold Extending through valve case is a valve stem portion 19v having at its lower end a tongue20 which loosely engages within the valve case the notch'oi groove 11 of the uppermost end of the valve stein. This looseness of engagement is to i permit the play of the valve before referred to. The valve stem portion19iis held from vertical removal by a removable pin 21 extending through' the neck of the case and tangentially to a peripheral groove 22 in said stem portion 19. Theupper outer extremity of the stem portion 19 has aiiixed to i it a handle 23 for oscillating the stem portion19 and the valve. From this construction it will be observed that the valve'having* some freedom of lateral or rocking movement and being subject to pressureautomatically accommodates itself toits seat. 1f the valve on one face becomes unduly worn or damaged the valve canfbe reversed and the other face placed against the seat. i

Because the valve is located on the lower side ofthe web or diaphragm thestu'fiing box of thel valve stem portion 19 is relieved of pressure and hence there isno danger of, i

leakage. y

One of the stems can be omitted and the device, if desired, made irreversible. Other' changes can be made without depart-ing from the gist of the invention as claimed.

` Ihave shown and described my invention as used in connection with a faucet but subiectto such restrictions as may be imposed by the prior art, the invention isnot confined to any particular use.

What 1 claim is: 1. The combination of a valve case having a single valve seat provided with a stem opening, a rotary reversible valve to seat on said valve seat, a spring for holding the valve ony said seat, a stem projecting into said opening toward the opposite rside of the f vvalve seat and means at that side for operatingthe valve, 4said. opening being 'of larger diameterthan the valve stemto permit play iio :2. The combination of a Valve case having a single Valve seat, a rotary reversible Valve `loody to seat on said seat having identical stems projecting in opposite directions, a

perforated union through which one of said stems extends, said valve seat provided with an opening into which either portion of said stem may he extended, and a spring for holding said valve on the seat when the valve is opened.

I The combination'of valve case having a single Valife'seat provided with a stem opening, a rotary reversible valve Aon the Copies of this partent may ne obtained for Vfive Vcents each, 'by

pressure side of said valve seat, identical stems one of which projects intosafd ope Washington, D. G.

ing toward the opposite side of the valve seat, the diameter/of said opening being greater than that orn the stem to permit lateral play thereof, a spring for holding the valve toward its seat, and detachable operating means engaging said stem at said last named,y side ofthe seat, the connection between saidl operating means and the stem being loose fitting to permit lateral play of the Valve, substantially as described.
